T0 at whom it may concern.-

Be it known that I, GABoR KoNIesrEIN, a citizen of the United States,residing in the city and in the county of San Francisco and State ofCalifornia,l1ave invented new and usef ul Improvements in Attachmentsfor Talking- Machines, of which the following is a specification.

My invention relates to an attachment which is especially designed foruse upon the movable arms used in gramophones or talking-machines andwhich arms are swiveled and turnablc, so that the points carried therebyconform to the movements of the disks by which the audible sounds aretransmitted.

It comprises combinations of parts and details of construction, whichwill be more fully explained by reference to the accompanying drawings,in which Figure 1 shows the application of my improvement, the novelparts being indicated in full lines. Fig. 2 is an end view of myimprovement. Figs. 3 and 4: are side views of same. Fig. 5 shows amodification of my invention.

In the present drawings I have only shown a snfiicient portion of themachine to illustrate the attachment of my devices.

A is a fixed arm, and 2 is an arm swiveled and turnable thereon. At theouter end of this arm is the U-shaped arm 3, which is swiveled andfreely turnable transversely to the end of the arm 2. The free end ofthe arm 3 carries the ring 4, within which is the needle-carrying socket5, so placed that when the arm 3 is turned about its swivel so as toengage the rec ord-disk the stylus or needle carried in the socket 5will rest upon the disk, and through the connections common to thisclass of machine and not here further described the sounds will betransmitted when the disk is revolved with relation to the contactingpoint. Considerable difficulty is experienced in the operation of thisclass of machines, because when a disk is to be removed or for otherreason it is desirable to disconnect the pin it is necessary to turn theswivel-arm 3 about its turnable support and swing it back upon the topof the arm 2. When the disk is in place, this swiveled arm is turned toallow the point to rest upon the disk, as before described; but itfrequently happens that this freely-turnable arm will slip from thefingers, and if the point drops upon the disk it will break the latteror spoil the matter which is carried by the disk, and when turned theother way it often drops upon the light tubular arm 2, with the resultthat the latter will be indented and defaced. It is the object of myinvention to prevent such accidents, and in order to effect this I forma ring 6, which has such interior diameter that it will clasp about therear portion of the ring 4; and may be secured by a thumb-nut orequivalent fastening, as at 7, so that it is clamped firmly upon thering 4:.

At one side the ring 6 carries a tubular socket 8. 9 is a stem slidablein this socket and normally pressed outward by a spring, as at 10. Uponthe end of the stem 9 is a head 11, which carries a rubber roller orequivalent soft buffer, as at 12. This buffer is extended downward withrelation to the surface upon which the point 5 rests, and by reason ofits extension if the turnable arm should slip or be allowed to drop therubber would first strike the plate and prevent a severe contact of thepoint 5 therewith. As soon as the apparatus is in motion, however, thepressure against the buffer 12 will be sufficient to compress the spring10 and allow the stem 9 to retract into the sleeve or support 8sufiiciently to allow the point 5 to properly engage the channels of thedisk. Upon the opposite side of the ring 6 is a buffer 13, which is soplaced that when the swivel-arm 3 is turned backwardly, as previouslydescribed, this buffer will rest upon the top of the arm 2 and willprevent any defacing of said arm by reason of the accidental dropping ofthe swivelarm thereon.

In the usual construction of these devices it is customary to turn theswivel-arm 3 by taking hold of the ring 4:; but this is somewhat awkwardand on account of its size it often causes the dropping of the device,as before stated. 14 is a handle of any suitable description projectingfrom the side of the ring and in such position as to be easily graspedby the operator, and by the use of this handle such accidents as hereindescribed may be largely prevented.

In Fig. 5 I have shown a modified and in many ways a preferred form ofmy attachment, since it is designed to prevent the arm 3 being thrownforward violently to cause such a compression of the cushion as wouldeven then allow the point or stylus 5 impinging injuriously on therecord-disk. Accordingly in this case the stem 9', carrying the cushion12, is slidable in a sleeve 8, arranged to one side rather thanradially, as in Fig. 2, of the ring 6. An expansion-spring 10 operatesbetween a flange on the inside of the sleeve and a collar 15 on the stemto retract the stem, and the latter carries a pin 16, movable in aV-shaped cam-slot 17 in the sleeve to control the movement of the stem.The upper end of the stem may be provided with a suitable finger-hold 18to allow its being easily operated. v In practice when it is desired tothrow the arm 3 forward preparatory to playing a piece the stem is firstpushed outward, compressing spring 10 and slightly turning the stem tocause pin 16 to engage in the shorter portion of slot 17. This insuresthe buffercushion 12' coming in contact with the recorddisk in advanceof the stylus, so that no matter how carelessly or violently the arm isthrown over the sharp metal point cannot injure the record. 'When thecushion rests on the record, a slight turning movement of the stem bythe handle 18 releases the pin, and the' spring will act to withdraw thecushion and allow the stylus to engage the record. Each time a record ischanged or the arm 3 is lifted the stem is turned to project the cushionoutward, and again after the return of the arm to its operative positionover a record the cushion is thrown and held out of commission in themanner described.

It is obvious that various other changes and modifications may be madewithout departing from the principle of the invention, and I do not wishto be understood as limiting myself to the specific construction hereshown and described.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a machine of the character described, the combination of asound-box movable toward and from the record and provided with a stylus,and means' operative to engage the record for holding the stylus out ofoperative engagement therewith said means being shiftable about the axisof the sound-box to disengage the record and permit the latter to beengaged by the stylus.

2. A talking-machine having in combination a sound-box movable towardand from the record, and provided with a stylus, arms by which thesound-box is supported, a device attached to the sound-box and ayielding member carried by the device and engageable with the record tohold the stylus out of operative engagement therewith, said deviceshiftable about the box as an axis to disengage the record and permitthe latter to be engaged by the stylus.

3. The combination with a talking-machine, the swiveled and turnable armthereof, of elastic cushions or buffers carried by the free end of theturnable arm and adapted to contact respectively with the. disk and withthe swiveled arm substantially as described.
